Players are ranked weekly based on their performance by finishing in cash positions in qualifying tournaments occurring over the previous 36-month period.

Qualifying tournaments are events with 21 or more players and a buy-in of $1,500, or other currency equivalent, or higher that are open to the public, and are not specialty or selected audience events.
